Responsibility for Worker's Comp Insurance Verification

Greetings and thank you in advance for your time in viewing and replying to my question.

I am a authorized motor broker (authorization from FMCSA. The nature of my business is to arrange shipment of vehicles for customers (shippers) utilizing auto carriers who are independent contractors to my company.

Recently I read something about possibly being liable in some way for the lack of Worker's Comp insurance by the carrier, when they are required to carry it for employees.

Does anyone have any information on this? Should I be verifying the Worker's Compensation for carriers that contract with me to deliver cargo?
